If his Drill Instructor stare doesn’t whip you into a hardened killing machine in his live action roles, his voice alone will make you unf-ck yourself and stand at the “Gaht-Dayum” position of attention.

1. You will get things done

There’s hardly any video game character more annoying than Legend of Zelda’s Navi.

The Great Deku Tree senses evil approaching Hyrule. Instead of waking up to the annoying sound of: “The Great Deku Tree asked me to be your partner from now on. Nice to meet you,” imagine if you heard banging on a trash can and The Gunny shouting “On your feet, maggot! Reveille!”

Hyrule would be saved faster than you can say “Ooorah.”

2. You will try much harder

One of the most critically acclaimed video games of recent history is Dark Souls III; and it’s praised for intense level of difficulty.

You rest beside the bonfire before making your way back to fight the Lords of Cinder. You think you’ve finally gotten good enough to make it to the next bonfire. But then you stupidly roll off the cliff.

The sting of hearing “Any f-cking time, sweetheart” would hurt far more than reading “You Died.”

4. You will be far more terrified

You listen to me and you listen to me good. I want that weapon. And I want it now. (Via Resident Evil 7)

What’s more terrifying than realizing that no amount of bullets will work on Resident Evil 7‘s Jack when you fight in the garage? That moment you realize that the Drill Instructor is in your face for something, you know you did wrong.

May God have mercy on your soul, for he will not.

5. You will not make the same mistake twice

His voice would have worked in classic gaming with Super Mario Bros. as well. You fight your way through until you reach World 1-4. You think you’ve got this. You’ve beaten Goombas, Koopas, and even stopped Bowser.

Guess what? you just wasted everyone’s time by going to the wrong castle! Now get out there and get the right d-mn one!

6. You will learn every aspect of the game

If you expect to play online, it isn’t your weapon but a hard heart and your skill that kills. If your killer instinct is not clean and strong, you will lag at the moment of truth. You will learn from Gunny. Gunny will teach you to hone your skills and be a true killing machine.

7. Best of all, it will be authentic.

In all seriousness though, the level of authenticity would rise with the inclusion of R. Lee Ermey into any game that has anything to do with war. Think of how real “Full Metal Jacket“ was because he took over the role of Gunnery Sgt. Hartman. This will happen to any game he’s included in.
